To azz whom', e may 4mwen.-

Be itrknown that I, LEONARD B. BUCHANAN, otWoburn, county oit' Middlesex, and State bf Massachusetts, have invented an Improvement in Automobile Horns, of Which the following is a specification.

This'inyention relates to horns adapted to be used'onV automobiles and elsewhere for' so ndlng a Warningsignal.-

" he invention has for its object the "construction of a horn which maybe operated by means arranged in proximity to the steer* ing Wheel of an' automobile, or other point ranged/see Figs. 4, 5 and more or, less remote from the horn, and its .operation may be continued by a .single movementof the operating-device as long as desired, so that in case the device is used 0n an automobile, the-chauffeur .may operate the horn without removing his hands from 4the steering-Wheel. r f jf The invention also has for its object the employment as a sounding-device for. the horn What I herein term a snapper-plate, which is arranged in conjunction -With l'a resonator, as, for instance, at the .apex of a horn `or thereabout, and Which, when vibrated is adapted to produce sounds of considerable volume and intensit and to provide a vibrating actuatingever for said snapper-plate, the movements of-Which are controlled by an operating-device adapted to be arranged more or less remote from the horn.

The inventions-lso has `for its object the employment of electrical means for eontinuously vibrating the` actuating-lever ofthe 'snapper-plate.

Figure 1 is a side viewof the automobile horn embod ing this invention, the operating-device t erefor being arranged in proximity to the steering-Wheel of an automobile.'

resonator, as, for instance, at the apex of the .l

horn orthereabout a snapper-plate a is aru Said plate consists of a thin, flat metallic plate, supported at its edges at one end only by a suitable frame a?, its opposite end being free, and said plate is formed with an indentation c3. Such a plate, when made of elastic metal,l is adapted by reversing the indented portion thereof, to produce short, sharp sounds of considerable volume and intensity. The indented portion thereof is reversed, as shown' in Figs. t and 5, by pressure applied tothe free end of the plate, and is permitted to assume Aits normal osition when pressure thereupon is relieve the sound being produced by both movements of the indented portion of vthe plate. The frame a? bearing said snapper-plate is arranged on 'a block at, or other form of support, to lwhich the horn is attached. As a means of vibrating said snapper-plate continuously, a vibrating actuating-lever is employed. Z) represents said actuating-lever. It is pivoted at Z1 to a baseplate, 62, and its free end extends over an extension-piece f0.5, secured to the free end of the snapper-plate, or, itn may extend directly over the free end of said late, the extension- .piece being omitted. Said vactuating-lever is here shown as a' circuit-makingland-breaking-lever, it having a contact-pen b3 attached to it, the free end of Which Ais movable into and outof engagement with a contact-point b4, supported by the plate b2.

' c represents an electro-magnet supported on the base-plate`b2, which is arranged at one side of theactuatingdever b, and said actuating-leveris constructed and arranged to serve as the armature of said electro-magnet, and

when the circuit c of said electro-'magnet 1s c osed, s idfarmature Yis causedl to -vibrate repea '-d y, like unto the operation of an ordinary vibrating electric-bell, the circuit c bein repeatedly o ened When the contact...

pen 5 dlsengages tie contact-point'b. The

circuit c extends to and includes a circuitclos'in .device represented at cl, Which consists o4 a simple form of make-and-break element having a finger-engaging member d by which it is operated. When the device is used on an automobile the hornl may be located wherever desired, and the circuit-operating device d' may be arranged on or in proximity to the steerin 'wheel e of the automobile`,so that While t e chauffeur holds the steern Wheel hel can reach the circuit-operatingde the circuit and thereby operate the horn.

I do not limit my invention to the particuvice and close 20 junction therewith,

the snapper-plate operated to produce sounds in quick succession.

I claim: A

l. The combination with a resonator, of a vibratory snapper-plate arranged in conjunction therewith, and a vibratory actuab ing-lever forsaid snapper-plate, substanl tially as described. 2. The combination with a resonator, of a .vibratory snapperplate arranged in conjunction therewith, a vibratory actuating-lever, and means for operating said actuatin lever, substantially as described.

3. The combinationnvith a resonator, of a Vibratory snapper plate arranged in cona vibratory actuating-lever, and means for operat-ing said actuatinglever, and an operating-device for said actuating-means, substantially as described.

4. The combination with a resonator, of a Vibratory snapper-plate arranged in conjunction therewith, a vibratory actuating-le ver, means for operating said actuating-lever, an operating-device for- Said actuatingmeans disposed at a distance therefrom and connected therewith, substantially 'as described.

5. The combination with a resonator, of a vlbratory snapperplate arranged 1n conjunctii therewith, a Vibratory actuatingle ver, and means lever from a distant point, substantially as described. v

6. The combination with a resonator, of a vibratory snapper-plate `arranged in conjunction therewith, ver, and means for repeatedly vibrating said actuating-lever, and a controlling device for said vibrating means located at a distant point, substantially as described.

7. The combination .with a resonator, of a for operating said actuatinga vibratory actuating-levibratory snapper-plate arranged in conjunction therewith, a vibratory actu a.tinglever means for vibrating said actuating-lever, and a controlling device for means, Which,`by a single continuous opera-l tion, causes said actuating-lever to repeatedly vibrate, substantially as described.

8. The combination with a resonator, of a vibratory snapper -plate arranged in con junction therewith, and to its support, and a vibratory actuating-lever for said snapper-plate, substantially as described.

In testimony whereof, I have signed my name to this specification, 'in the' presence of two subscribing witnesses.
